Astudent tested a sample of carbon (c) by combining it with water. there was no reaction between the carbon and water. the student concluded that carbon must be a group 18 element, since it was unreactive. is this conclusion correct? why or why not? no. the carbon probably did react, but did not give off any signs or indications of a chemical change. no. just because carbon did not react with water, does not mean it wouldn’t react with a different compound. yes. the student can make a reasonable conclusion based on one experiment. yes. water would react with almost every element, except group 18 elements.

Will give brainliest it is a lab from k12 here is the linkfor each metal that participated in a chemical change, write the type of metal it is, based on your examination of the periodic table. type your answer here. (score for question 3: of 5 points) were there any metallic compounds that did not react with either the acid or the base? write the type of metal, based on your examination of the periodic table. type your answer here. (score for question 4: of 5 points) make a general statement about the reactivity of the metals in this experiment. type your answer here.
